Title: Highly efficient alloy powder synthesizing method by mechanical alloying method
Inventor: KOBAYASHI KEIZO
IPC: B22F1/00
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To shorten the required time of milling and to synthesize an alloyed powder with high efficiency by adding a light element and performing mechanical alloying. SOLUTION: At the time of synthesizing an alloy powder by mechanical alloying, an element of atomic number 8 or below, preferably C or B, is added to raw material elements. The additive quantity of this element is regulated to a degree where this element does not act as a constituent element of the alloy, e.g. 0.01-10 mole %. This light element is mixed rapidly and finely into the alloy powder to form a homogeneous structure in a short time, increases hardness abruptly to improve powder effect, and further reduces the adhesion of the alloy powder to a vessel or balls due to electrostatic action or the coagulation of the alloy powder. By this method, the time needed to synthesize the alloy powder can be shortened, and increase of efficiency and reduction of cost can be attained.

Title: Improvement for performance of fluid pump
Inventor: SATOU YOSHIO
IPC: F04D29/22
Filed: 1982-02-17
Abstract: PURPOSE:To increase a velocity head at the outlet of an impellor, reduce the torque of the impellor and improve the performance of the pump by a method wherein a flow path area is increased into up-and-down direction on the way of the flow path for the pump impellor. CONSTITUTION:In case the flow path of the pump impellor is expanded as shown by the flow paths 4, 5 in the diagram, the amount of flow is increased and a large velocity head is generated at the outlet 3 when the pressure of the fluid at the flow paths 4, 5 is delivered to the outlet 3 smoothly, and the performance of the impellor may be improved. When the fluid, flowed out of the outlet 3 of the pump impellor, is flowed out with a large flow speed due to the curve reverse to the revolving direction of a vane, the torque becomes very small or negative and the performance of the impellor may be improved because  the torque of the pump is determined by the difference of angular momentums.

Title: Receiving frequency selecting method in rds receiver
Inventor: RYU KOICHI
IPC: H04B1/16
Filed: 1990-01-31
Abstract: PURPOSE:To receive positively a same network station of a different regional network by storing a PI data of a current receiving station in response to a command and applying a prescribed processing when the transmission system is the B system. CONSTITUTION:A processor of a controller 13 stores a PI data of a current receiving station into a memory 14 in response to a command.

The presence of another receiving station based on the selected AF data is detected by monitoring a station identification signal from a station identification circuit 17. Succeedingly, the processor uses the frequency of this receiving station as a new receiving frequency when the PI data obtained from a broadcast wave of this receiving station is coincident with the PI data stored precedingly except the area code. Thus, a same network station of a different regional network is positively received.

Abstract: PURPOSE: To separate component pulse strings by sequentially erasing a mixed pluse string of several pulse strings different in period, by generating pulse strings with a period equal to the maximum interval between two adjacent pulses in the mixed pulse string.  
     CONSTITUTION: Mixed pulse string P is formed of pulse strings P 1  to P 3  in several sequences of different repetitive periods (τ 1 ) to (τ 3 ) [(τ 1 )<(τ 2 <(τ 3 )]. Then, a pulse string is generated which has a repetitive period equal to the maximum period between two adjacent pulses of this pulse string P. Next, the pulse-string erasing method erases pulse string P 1  from pulse string P by using this pulse string. Moreover, pulse string P 2  is erased from the mixed pulse string of remaining pulse strings P 2  and P 3 . The finally-remaining pulse string agrees with pulse string P 3 . Consequently, pulse strings P 1  to P 3  constituting pulse string P can be separated from it.
